I want to create a xAPI compatible LMS which would share data from a LRS.
I wanted my UI to be completely separate from LMS ie I want LMS as REST services but I am unable to find a way to play/view SCORM or xAPI content files yet.
Can please someone elaborate how would this be possible?
Hi xAPI is endpoint based. Meaning the content has a targeted server in which it communicates with. There is nothing for you to implement on a traditional LMS.
SCORM searches the DOM on the LMS for a JavaScript public object called API_1484_11 or API in SCORM 1.2. This requires you to expose this runtime API value for the content to communicate with.

I'm new to building APIs, I made the first one using an MVC framework: codeigniter, with chris kacerguis rest implementation.
I'm not really sure this was the best think to do because I believe maybe the framework is not that "slim" or light just to API's purposes.
I plan to do a mobile App, an admin and a website so the three can consume the Api's services.
Is it a bad idea to have the API, the website and the admin on the same project? which are the pros and cons? or the best architectural approach?
Otherwise I will have: One Codeigniter project for the API and Another Codeigniter project for website and admin
thanks
You can create folders in "controllers" folder to organize your project and use the same project/env configuration :
controllers/Home.php
controllers/api/MyApi.php
controllers/admin/Admin.php
Edit : You will share models and libraries too.
In my project I realized 2 types of controller - REST and API. Admin js gui work with REST, other world work with API. You can do it simply with silex framework, a little brother of symfony.
The purpose of building a REST API so that you only have to build one project for your business model. This allows you to construct any number of applications on any platform, only requiring you to consume the API in different ways. This essentially separates/decouples the user interface from the business logic, and vice versa.
You should create separate projects for the REST API and each UI project should also be separated projects. This allows you to change the underlying code, language and platform in any one of the projects without breaking any of the other projects as long as the API signatures remain the same.
For example, you could have a live version of your website built using Codeignitor while developing another septate project using AngularJS. When your AngularJS project is complete you would simply swap out the project on your server (or create an entirely new website or server) still allowing you to use the other if required. Additionally, you may decide that you would like to move the API onto a different platform, language or database, develope it and swap the implementation when finished causing no changes to any of your UI projects assuming you have not changed the API signatures.
I have developed one spring based java web application. In my project it is requirement to use alfresco as a CMS. For this I want to integrate this application with alfresco. So I decided to use alfresco java API's.
http://dev.alfresco.com/resource/docs/java/
But I am not getting how to use those API's to complete backend work of my web application. Suppose I would like to submit one form having user name & password fields in it. After click on submit button how can I handle request in backend so it will use Alfresco java API to process request and store details in database.
I have to do many operations in my project like upload file, play with documents, Submit different forms. view those forms etc.
My first question is am I going in right direction by using alfresco java API's. if yes then how can use those API? is there any other way to do this?
Any help would be appreciate!!!
Thanks in Advance,

Well, based on my experience, Alfresco is an excellent ECM but not suitable for being a CMS.
Apart from that, it is difficult to give suggestions, starting from the very general overview you have given, but things like user name and password have little to do with an ECM and storing of data in a database.
You have two options available.
One involve using the Web Content Management Quick Start, it's a Spring Surf app you can (not easily in my opinion) customize for your needs.
The other solutions, if you have an existing web app, rather than develop your own API have a look at CMIS, I have put a simple wikipedia explanation, you can dig further from there.
Then, when you are ready, have a look at Alfresco CMIS first, and the most used Java API for doing CMIS call, which is Apache Chemistry
CMIS, in its intent, guarantee that Alfresco could be replaced with any other CMIS compliant ECM. You can easily integrate Apache Chemistry in your Spring app.
I have experience with other enterprise CMS's like Teamsite & Tridion, but no hands on experience with CQ5. I'm wondering, how is CQ5 usually integrated with a large site that has content & functionality? Functionality defined as pages are generated with data from a non-CMS repository or webservice.
My question is, is CQ5 content read in as a back-end service? I know the API is http based. But is that API typically called from server or client? For my example, lets say I have a page that is from mostly driven from a web service that is linked to some non-CMS enterprise system, but I want the footer & right rail to be "content" so that the users can change it easily. At what point would the the different page sources typically be combined?
I'm wondering because I work with asp.net. I know the CQ5 is Java, so I would expect that most cusomters are java shops, but I would think that the HTTP would be easy to consume for an ASP.net site, if it is really just another backend webservice.
Your question is really not all that clear to me to be honest. So I'm going to answer this rather broad.
To answer your question about the different page sources:
The client usually initiates a http or json request to the server (although server to server calls are not uncommon in case of extended infrastructure) and the server simply executes the necessary calls (using the apis) and delivers the answer to the request. But at the point of request return, all calls to the api have been made by the server, and the server is just returning rendered html or json, or whatever structured form you want to have your data and/or content in.
A page consists of various components. Some components are fairly static. Others are very dynamic and pull their data for example from a webservice, or external database or even another cms. The combining of these resources happens upon the rendering of the page which in its turn was triggered by a request for that page. The obvious exception is ofcourse the dispatcher caching system which will return a cached version of the page if possible. But in short, all the rendering and api calls are made server side.
CQ5 is fairly flexible since it's split up into 2 instances. The backend (author) which is where the actual authoring of pages happens. And the frontend (publish) which is basically the frontend, and does the actual rendering for a client (usually).
Wether you choose to use the publish instance a backend service is just up to you to be honest. I've seen cq5 used as what it was ment for (cq5 being the frontend), and I've seen cq5 used as a backend service (for example: as a backend service provider for hybris). And I've seen the combination, where one part was used as backend service for another system, and the other part was used for a public website frontend.
CQ's rich HTTP API (based on Apache Sling) gives full access to the CQ content in various formats including JSON and XML, so integrating CQ content in other systems is easy.
In the other direction, you can use Sling's ResourceProvider mechanism to access external content and make it part of the CQ content tree. See "custom resource providers" in the Sling Resources docs at http://sling.apache.org/documentation/the-sling-engine/resources.html .
I have to create a project in iPhone which uses the Tin Can API. The Tin Can API is an advanced distributed learning process.
I have no idea about where to start in Objective-C.
I have read the site http://tincanapi.com.
For implementation, I have some basic questions:
How and to create my own LRS?
How Tin Can API can communicate with my own LRS and LMS with ASIHTTPRequest programatically?
There are two parts to TinCanAPI at play here. I'm suspecting you only need to handle one of them on iPhone. One part is the client-side that sends the statement date to the second part (the LRS server-side). It would be very odd to create the LRS server part on an iOS device, so I'm going with the thought that you need to send TinCan statements from an iOS device to an existing LRS.
An LRS accepts statement data via a REST interface and this data can be POSTed using a standard NSURLConnection or using AFNetworking. There are a couple of options for abstracting all those calls with a library one of which is a new OSS version of the basics appearing very soon from Rustici Software found here http://rusticisoftware.github.io/TinCanObjC/. There is no link for it just yet, but feel free to contact me for more details and I'll update this answer with the link as soon as there is a public link.
For your specific questions:
1.) You can create your own LRS by understanding the spec document and creating the REST endpoints as specified. This is not a trivial undertaking by any means.
2.) Your best bet is to use an SDK or simple GET and PUT/POST statements from AFNetworking to the TCAPI endpoint.
I'm looking for a server side component, preferably java, that will allow me to subscribe to pubsubhubbub feeds through javascript. I understand that subscribers are server side applications in the standard rest/pubsubhubbub format, but Google seems to have created a ajax bridge that looks quite handy.
Unfortunately, I'm dealing with data that simply cannot leave our servers, let alone go through Google's.
Is anyone aware of a (preferably free) server side proxy for pseudo javascript pubsubhubbub subscribers?
Reference: http://code.google.com/apis/feed/push/docs/index.html#hiworld
I know for a fact that Kwwika and Pusherapp are working on this. I can intro you with these guys if you want.
If not, I believe this should be relatively easy to build with stuff like Node.JS for example. This code on Github should be a good first start. Things like this have been built with it.
We (superfeedr) are trying to get more people building similar things...

There is a java implementation]1 of the subscribe part available. But the hub-part hasn't yet been implemented in java which is needed to subscribe to the feed which should be private. For the javascript(jquery) part I would just use simple long-polling.

I don't think a free solution like that exists (yet). Even google's push API isn't open yet.

There isn't yet an implementation of the HUB-part of the pubsubhubbub protoccol. But if it is internally I also don't think you need this kind of fan-out the hub(specification) is offering(broadcast to other servers).
I think you could just use A comet framework like Atmosphere to suspend connection and broadcast feed diff. I think this can be written quick with the Atmosphere framework(1 day you will have a working prototype).
You can see an example using a combination of Superfeedr and Kwwika within a web application that lets you subscribe to any RSS feed or track keywords within RSS feeds here:
http://superfeedr.kwwika.com
And you can get the source code in GitHub here:
